[PP2-2-4-1] Radar equation

The radar equation is a measure of the received echo at the sensor. It defines what proportion of the transmitted energy is returned from a target. It is a function of the range between the antenna and the target, the antenna gain and the radar cross-section of the target. Mathematical expression that describes the average received signal level, compered to the additive noise level, in terms of system parameters. Principal parameters include: transmitted power, antenna gain, noise power, and radar range.
